It also shows some doubling on the obverse, could be machine but not the main focus to the coin. the coin is currently sent out for classification by cherry pickers and then will be slabbed via PCGS once its confirmed.
Years ago(around 1977) I bought a 1937 d over d from a dealer and he had it as a 1937-d. I put it away and now I can't find it. I started this in a big capital holder for buffalo nickels. Maybe when I clean out my room I might find them plus other stuff. Dean 295
I'm not sure how to price it either. Being that it is one of a kind so far. Someone has offered me 5000.00 if and when it comes back slabbed as an OMM D/S
Thanks for the info -- if you're successful in getting it attributed, I suggest you post it to the Buffalo varieties website CoolKarma has put together at Coins.cool karma.com [there's no space in the website -- just in my IPad]
